14-year-old Kazeta Izaemon is hit by a limousine on the way to school, and is brought to a hospital by the limo's owner, a rich woman by the name of Momoizumi Hanae. Unfortunately, the doctors mistake Izaemon for a patient in queue for a sex change operation... but is it a mistake? Or has Hanae actually launched a devious plan to make Izaemon her lesbian love-slave?
